Linux Kernel Daily: KVM Hardening and Late-Cycle Net Fixes

Late 7.3 release-candidate activity centers on stabilization, with KVM closing guest-triggered host bugs and networking unwinding recent regressions. Smaller device-tree, power-management, crypto, and sysctl fixes round out release risk reduction.

Good morning, it's Friday, October 2nd, 2026, you're listening to Linux Kernel Daily.

The lead pattern is late-cycle hardening: virtualization fixes stop a misbehaving guest from harming the host, while a broad networking pull cleans up recent regressions before 7.3.

First, virtualization. Tracked as commit A nine four zero B zero three, the main K V M merge fixes several cases where the guest could deliberately cause host problems on x86. Failed virtual machine launches could drop pending T L B flushes, and actions tied to control fields now have to be redone if launch fails.…

Second, networking stabilization. The net pull for 7.3 release candidate six addresses checksum offsets, transmit queue mapping caps, and a use-after-free in page pool recycling. It includes Wi-Fi fixes for an out-of-bounds read and oversized fragments, plus Bluetooth locking and Ethernet driver corrections. The…

What's next is verification: test nested virtualization, wireless, flow tables, and device-tree overlays, with slower upstream traffic expected around Plumbers next week.

Thanks for listening, we'll update you tomorrow.
